The Original — RZ M1 Neoprene Mask Since 2010

The RZ M1 Neoprene Mask is where it all started. Launched in 2010 as the first RZ Mask product, the M1 Neoprene paved the way for 3+ million masks sold worldwide and a lineup that now spans certified respirators, patented 3-strap systems, and advanced filtration technology. The M1 is still going strong — and for good reason.

Built from high-quality neoprene that keeps you comfortable in cooler temperatures, the M1 features the same F1 Active Carbon Filters that deliver 99.9% filtration down to 0.1 microns, dual one-way discharge valves, and an adjustable nose clip that eliminates eyeglass fogging. Simple, proven, reliable.

Why Neoprene?

Neoprene is a flexible, durable synthetic rubber that conforms to the face for a comfortable, consistent seal. Unlike mesh masks, neoprene provides additional warmth in cooler temperatures — making the M1 the preferred choice for cold-weather outdoor work, fall and winter landscaping, construction in cooler climates, and any environment where a warmer mask is an advantage.
